Well it's done. Let the 7th coat bake for about 3 hours just to see if it made a difference. It's very glossy, more evenly coated and almost black. Under a very bright flashlight it's a deep mahogany color, but under normal lighting it just looks black. Didn't take any more pics because I just didn't feel like messing with it. It probably wouldn't look any different from the last pics anyway. Overall I'm beyond thrilled with the results. Although time consuming, it was not difficult at all. I'm thinking with normal use and maintenance, it will just get deeper, smoother and more stick resistant.
Here's what I did. I differed slightly from the original method to save a little bit of time.
Step1: Wash thoroughly with hot soapy water and steel wool. Dry.
Step 2: Run through self clean cycle in oven.
Step 3: Heat to 200˚ and apply a thin coat of flax oil taking care to wipe off all excess.
Step 4: Place in oven, crank to 500˚ and bake for one hour.
Step 5; remove from oven, let cool and repeat step 4 until 7 coats have been applied, letting the final coat bake for 3 hours.
